1. GPS_Tracking_Cat_Collar_XIAO_ESP32-C3 GPS_Tracking_Cat_Collar_XIAO_ESP32-C3 Public

   An Arduino project to log GPS data to a MicroSD using the tiny XIAO ESP32-C3. The components are small and light enough to fit around a cat collar! Now we know where the cat runs around at night :-)

   C++ 10 2

2. FindEachOtherCompass_ESP32-C3 FindEachOtherCompass_ESP32-C3 Public

   An Arduino project to create a compass that not only points North, but also points to another person. This is very useful for outdoor teams sports like Airsoft.

   C++ 9 2

3. Airsoft-HUD Airsoft-HUD Public

   Transparent HUD for an Airsoft gun that shows how many BBs are left in your magazine and keeps track of your number of kills and deaths during a match. A XIAO ESP32-C3 is used together with a SSD13…

4. ESP32-CAM_With_SSD1306 ESP32-CAM_With_SSD1306 Public

   A simple Arduino project to show how to use a SSD1306 OLED display with ESP32-CAM. The reason why this is interesting is that the SSD1306 uses I2C, not SPI. Since the ESP32-CAM doesn't have I2C pin…

5. SimpleBLE_ESP32-C3 SimpleBLE_ESP32-C3 Public

   A simple Arduino project to show how to setup a BLE Peripheral device and a BLE Central device, and how to send values from the Peripheral to the Central using Notify

   C++ 2

6. ContinousAnalogRead_ESP32-C3 ContinousAnalogRead_ESP32-C3 Public

   A simple Arduino project to show how to continously read analog values directly from the ADC (analog to digital converter) on an ESP32-C3. This is much much much faster than calling analogRead(), s…
